[jira] [Comment Edited] (OLINGO-1276) Client incorrectly parses
stream with left brace in JSON string
[ https://issues.apache.org/jira/browse/OLINGO-1276?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16609037#comment-16609037 ]

----------------------------------------------------------------
I have encountered a very similar issue but with a JSON string containing a right brace '}' character. For example in this response ...
{"@odata.context":"$metadata#Cubes(Name)","value":[\\{"@odata.etag":"W/\"c24af675e00a3f95ef63f223fb9c2cc8d6455459\"","Name":"}Capabilities"}]}
This is when using the IBM Cognos TM1 REST API - all control object names start with '}'.
The ClientEntitySetIterator method logs an error but the iterator ends normally i.e. hasNext() returns false. Not sure if the proposed fix covers this case as well.

> This bug has already been reported in February 2015, see [https://github.com/apache/olingo-odata4/pull/4.] I didn't notice the fix linked to this Github issue before I started coding my own fix, but it looks pretty similar.
